drm/msm/a4xx
error handling
a4xx_gpu_init
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a4xx: fix error handling in a4xx_gpu_init() This code returns 1 on
error instead of a negative error. It leads to an Oops in the caller. A
second problem is that the check for “if (ret != -ENODATA)” cannot be true
because “ret” is set to 1.
